这个范例演示了如何通过几何图形计算体积,涉及立方体、平行四边形等立体几何概念。构造中使用了Random、Shuffle、Join等GeoGebra命令,以及Polygon、Segment等对象。适合初中及以上学生用于学习体积计算和几何作图技巧。

GeoGebra 命令及参数

  1. Random(1, 4) → randoEinheit
  2. Shuffle(Sequence[i, i, 1, 20]) → RandoExListHelperHelper, {7, 2, 17, 9, 1, 5, 11, 16, 13, 4, 12, 14, 6, 10, 15, 8, 3, 19, 18, 20}
  3. Join({{9}, RandoExListHelper}) → RandoExList
  4. If(ex < 11, 1, 2) → Typ
  5. If(ex < 11, ex, ex - 10) → Step
  6. Textfield(input1) → InputBox1
  7. Textfield(input2) → InputBox2
  8. Polygon(PtopLeftCornerFeedback, PtopRightCornerFeedback, PbottomRightCornerFeedback, PbottomLeftCornerFeedback) → rectangleCorrect, ptopleftcornerfeedback, ptoprightcornerfeedback, pbottomrightcornerfeedback, pbottomleftcornerfeedback
  9. Segment(Q1, Q1') → q1
  10. Segment(Q4', Q1') → q2
  11. Segment(Q2', Q1') → q3
  12. Polygon(Q1, Q2, Q2', Q1') → G, q3', q4', q2', q1'
  13. Segment(Q2', Q3') → h
  14. Segment(Q1, Q2) → a
  15. Segment(Q2, Q2') → b
  16. Segment(Q3', Q2') → c
  17. Element(ListCorrectG, Step) → AuswahlG
  18. Element(ListCorrectH, Step) → AuswahlH
  19. Element(ListCorrectA, Step) → AuswahlA
  20. Element(ListCorrectB, Step) → AuswahlB
  21. Element(ListCorrectC, Step) → AuswahlC
  22. Element(ListCorrectV1, Step) → AuswahlV1
  23. Element(ListCorrectV2, Step) → AuswahlV2
  24. If(gesG, "G = ", If[gesH, "h = ", If[gesA, "a = ", If[gesB, "b = ", If[gesC, "c = "]]]]) → solhelper1
